To all whom it may concern: 7

Be it known that LEMIL P. SIARY, a citfizen of the United States, residing'atCedar Rapids, in the county of Linn and State of Iowa, have invented a new and useful Internal-Combustion Engine, of which: the following is a'specificatio drawal of the pistons "from the cylinders, wherebythe cylinders are caused to rotate, A further object of theinvention' 1s to provide an engine of the character set forth, whereby a smoother running engine 'is'obtained than heretoforeYand which is extremely economical in operation, for the reason that greater power is obtained with lessfuel; i

With these and other objects in View,"

which will appear as the description proceeds, the invention consists in the novel features of construction and combination of parts, all of which will be more fully described hereinafter and finally pointed out in the claims.

The drawing accompanying and forming part of this specification illustrates an end view of the housing of an engine in which is embodied my invention.

In the embodiment of the invention herein illustrated, 2 designates the frame or housing of an engine, in which is mounted for rotation a driving shaft 3 for transmitting power from the cylinders to the working parts of the engine- To the shaft 3 is secured an arm P'WhiOh extends across the 5 1. fiT A e M U$T ENGI E apair of lugsor ears 8 carried by the cylinder. One arm of the bell crank is pivoted at its end to the piston rod 9, while theother arm ofthebell crank carries atits free end a roller 10 for apurpose'to be presently described. 'Securedto the housing '2 is a sys- Y 1 p c i q ti e r l t t Patented Oct. 14,1919. I

tern of cam track guides, shown herein'as formed ofa pair of inner member'sll and '12 located 'at opposite sides'of the axis of rotation of the shaftf3 and each extending a distance equal to approximately :one-

fourth of the length of the path oftravel of the cylinders,'and anouter' member 13 also extending approximately one-fourth of the length of thepath of rotation of the cylin- 1 ders, themember 13 being located'opposite one of the gaps formed betweenthe ends of the members 11 and'l2. The track guides .11, 12 and 13 'are eccentrically disposedwith relation to the path of travel of the cylinders V and also-with relationto each other,,as shown in the drawing.

Secured to the housing2,1 at the exterior thereof, isa fiat springili having secured theretofatits free end a plunger 15 which PIOJBCtS through an opening in' the hous- Jing'2 into the path of the outer end of the piston rods 9-at the properpoint with relationto the track guides 11,-12 and 13. The plunger 15 is provided with an inclined surface 16 over which the piston rod is adapted to ride and the longer end of which is adapted toform a stop for preventing the piston from beingv forcedoutwardly under the force of the explosion, as hereinafter described.

In the operation of the engine, thecylinders being in the position shown in the drawing, the cylinder at the lower portion of the figure is at the point in its travel where the charge is under compression, the spark being set to ignite the charge at this point. In this position the end of the piston rod abuts against the spring-pressed plunger 15 so that when the explosion takes place the piston is held against withdrawal from the cylinder and the latter is thereby caused to rotate in the direction-shown in the drawing. This rotation carries the roller 10 into contact with the outer face of the track guide 11, which, by reason of its cam action on the roller, forces the piston inwardly, the piston reaching the limit of its innermost movement just as the roller passes out of engagement with track 11. 'The roller 10 then engages the inner face of the track 13 and is gradually force'd toward the'axis of rotation of the arm 4, thereby withdrawing the piston and drawingia charge into. the cylinder. When the roller 10 has reached the end of the track '13 the piston mama to the path of travel of the cylinders, a shaft extending through the casing, an arm operating .on'ithefs'haft, said arm having connection with the cylinders, pistons in the cylinders, piston rods connected to the has reached the limit of its outward stroke f1 pistons, bell crank levers having connection and the roller then passes into engagement w-1th';--t11e :plston rods, a roller on .one exwith the outer face of the track ,guidevl2, tremity of each-bell crank lever and operatwhich again forces the piston inwardly,

thereby compressing the charge in the cylinder. When the roller has reached the end ofthis track 12 the charge is fully compressed and the outer end of the piston rod has passed over the spring-pressed plunger and is thereby locked against withdrawal, whereupon the above described operation is repeated.

It is believed unnecesary to show herein the carbureter and ignition system, since these features are well understood. If desired, the arm 4: may be so, constructed as to form the gas and exhaust manifold.

While I have described in detail the structure herein illustrated, I do not desire to limit my invention to the precise features of construction shown, as I am aware'that many mechanical changes may be made without departing "from the spirit and scope of the invention as set forth in the appended claims.

Having thus described my invention, what I claim is:

1. In an internal combustion engine, a stationary circular casing, traveling cylinders supported within the casing, track guides eccentrically disposed with relation i Witnesses -ing on the track guides, and a spring pressed lug extending through the casing and cooperating with the piston rods for preventing rotary movement of the cylinders, in one direction.

2, In an internal combustion engine, ,a stationary circular casing, traveling cylinders within the casing, each of said cylinders having integral lugs, a .bell crank lever pivoted to each of said lugs, pistons in the cylinders, said pistons havingic onnection with the bell crank levers, means on the oppositeends of thebell crank levers for -.engagin;g the inner wall of the casing, for causing movement of the p1stons,.a sprlng pressed plunger having an incllned surface,

extending through the casing, and within the path of travel of the cylinders, said plunger adapted to cooperate with the cylinders for preventing rotary movement of the cylinders 'in one direction.

In testimony that 'I claim the foregoing as'my own, I have hereto afiixed my signa- ,ture in the presence of two witnesses.
